The Post-cataract Astigmatism According to the Tightness of Suture

ABSTRACT

The post-cataract astigmatism was evaluated clinically between the groups with loose and tight suture in 47 patients(48 eyes) who had taken intraocular lens implantation with extracapsular cataract extraction. The results were as follows; 1. The post-cataract astigmatism in the tight suture group was significantly larger than the loose suture group in the early postoperative period. 2. There was no significant difference of the degree of astigmatism between the groups with loose and tight suture at postoperative 8th week. 3. Postoperative astigmatism was smaller than preoperative astigmatism in both groups at postoperative 8th week. 4. Decreasing velocity of with the rule astigmatism after operation is similar in both groups. Changing time of astigmatism axis Tight suture group; 6th-8th week. Loose suture group; 3rd-4th week.
